thanks More come in next week

[Massman]

The CPUs are available in Vietnam?!

[flanker]

but much better than my R15. Seems, at my side its VID and TDP issue. Higher VID, higher temps--> higher TDP than 65W?

Your R15 seems as Kaveri around the 7850K default score (3.7 GHz)

 

Next week Il be back with benchmarking Excavator again.

I just got sample .

I appreciate how availability has been asked numerous times in this thread and @hiepgia was the only one to even address it.

X4 845 is (supposedly) 5+ pieces in stock here in CZ. http://www.czc.cz/amd-athlon-x4-845/186690/produkt

[Massman]

Available through Amazon now as well: http://www.amazon.com/Advance-micro-device-Near-Silent-AD845XACKASBX/dp/B01BF376EI/ref=sr_1_1?ie=UTF8&qid=1457409738&sr=8-1&keywords=athlon+x4+845

 

Too bad I'm flying out on the 15th. I guess I'll get one when I'm back.

@Massman

Just got back from the store binning some g4400 for Pro cup 32M stage, and found one X4 845 there

 

Fastest in AMD 32M 5Ghz before Flanker come back with his better score hahah:

http://hwbot.org/submission/3151415_lucky_n00b_superpi___32m_athlon_x4_845_11min_20sec_358ms

 

I don't expect much overclockability from this design, IIRC AMD mentioned that CZ's design will sacrifice frequencies to made it more efficient in the lower TDP range. This one has it's turbo rated at 3.8Ghz 1.475V VID, and mine already need 1.5V to pass 105Mhz BCLK (4Ghz-ish), so the default 3.8Ghz could be it's optimal frequency range vs volt vs TDP already.

 

Expect more test next week, need to write some other articles first

[xxbassplayerxx]

Is that NB frequency correct or does it throttle?

[Lucky_n00b]

BIOS also noted it as 1.3Ghz on default, with 1.175 VID. Upper range on mine around 1400-1450Mhz is @ 1.35V VddNB, 1475-1500Mhz failed to boot.

 

According to geekbench 3 memory scores, this NB affects memory performance greatly.

Nice find!

 

Shipping directly from Amazon is listed as temporarily out of stock as expected but others look to be able to ship from international (from US) taking about a week.

Silly AMD... can never get the NB right

 

Do you have unlocked control over this? Maybe these locked chips will consist of freezing to try to get NB up high.

Both the CPU Multiplier and the NB are hard-locked, the only way you're increasing these is the BCLK, no other way.

 

I found something strange though, in the BIOS version I tested on, the highest CPU Multiplier available is 35(not the 38x Turbo Multi). Since this would probably meant that the 38x is the Turbo state, I need to put AUTO in the CPU Multiplier, and OC BCLK from here. But larger than 109 Mhz BCLK, My CPU constantly dropped it's multi to 35x in OS, no matter what settings I put on. I even tried putting a pot and dropped the temp to 0C, no difference.

I was keep the turbo at "auto" and after raise the BCLK. Boot into the WIndows and after via TurboV. Did you had IDE mode or AHCI as at mine side?

880K will be based on Excavator? Sounds like AMD Pi records are just around the corner if so.

I see, I didn't try turboV since my version is not working. This is under AHCI mode, I've managed to boot straight from BIOS at around 114Mhz though, but with 35x multiplier.

 

On XP IDE, Highest I've boot into OS was 120Mhz, but with lower CPU multi and low memory multi.

Based on that slide that said 16x PCIe 3.0 lane and 4MB total L2 Cache, it will be steamroller-based. Excavator only have 8x PCIe 3.0 and 2MB L2.

 

I don't know if I had bad carrizo sample, but if hitting 4-4.1Ghz requires extra volts up to 1.55v, I might understand why AMD didn't make a K-series for Excavator athlons.

 

This is like a mobile chip made into desktop, which not designed to hit big clocks. Not to mention this is similar 28nm process node as steamroller, further miniaturized by optimizing for density. This most likely hurts the overclockability and clock potential, the efficiency has a big price to pay it seems(not going to stop me from freezing this chip though ).

[flanker]

There is AMD TurboV (its working only at AMD platforms AM3+, FM2+ ) Hope it helps you

[Massman]

Good information, @Lucky_n00b, and congrats on the fastest "5G" AMD 32M

 

It's quite clear that the Excavator is a design for mobile and not for desktop. The overclocking capabilities make me think of the Kabini chips which also have good performance clock-per-clock (even with single channel!) but lack the frequency to be really useful.

880K is a Godavari (Kaveri Refresh).

 

Funny fact: this was already announced in September 2015 http://www.techpowerup.com/215881/amd-readies-a10-7890k-a8-7690k-and-athlon-x4-880k-socket-fm2-chips.html. Talk about being late to market (actually haven't seen them yet).

[flanker]

Maybe its logic reason, if I heard Bristol Ridge will be little different core than this FM2+ Excavator....

Just read this (the AMD guide for Family 15h Model 60-6Fh): http://support.amd.com/TechDocs/50742_15h_Models_60h-6Fh_BKDG.pdf

 

On page 85, I saw that on this models AMD might already given some DDR4-2400 support on its DRAM controllers(DCTs). This would pose a problem though, DDR4 has been evolved quite quickly these days, and DDR4-3000 should be found quite easily.

 

Would've been a shame if AMD only have DRAM Ratios up to 2400 while its competitions can do 3600+ daily, really hope for the sake of their APUs AMD support higher DDR4 clocks..

[Massman]

I wouldn't be too concerned about that, Alva. Remember that back in the Phenom II days the official specification for the memory frequency was DDR2-1066 and DDR3-1333. DDR3-1600 was already widely available (and not even officially supported by Intel at the time).
